# s-brain: reiterating perspectives: the Silhouette Illusion

<< If the foot touching the ground is perceived to be the left foot, the dancer appears to be spinning clockwise (if seen from above); >>

<< if it is taken to be the right foot, then she appears to be spinning counterclockwise >>

<< the way people perceive the Silhouette Illusion , a popular illusion that went viral and has received substantial online attention, has little to do with the viewers' personality, or whether they are left- or right-brained, despite the fact that the illusion is often used to test these attributes in popular e-quizzes >>

<< Niko Troje says that a reported preference for seeing the silhouette spinning clockwise rather than counter-clockwise is dependent upon the angle at which the viewer is seeing the image >>

<< Our visual system, if it has a choice, seems to prefer the view from above >>
